Abstract

The invention provides a superconductivity copper foil tape, which has good ultra-high conductivity and direct welding capacity, is applied to key parts of ultra-precision electrical and electronic components, and is not easily oxidized. The superconductivity copper foil tape is characterized in that a conductive self-adhesive layer is attached on the upper surface of anti-sticking silicone-coating oil paper, and tin-plated copper foil is attached on the upper surface of the conductive self-adhesive layer. The copper foil tape which is coated with a conducive adhesive with ultra-low resistance leads the copper foil to be convenient to be bended and crimped, has ultra-high conductivity and direct welding capacity, is not easily cracked, and is suitable for electronic components and punching type processing.
